2015-04-05service: remove unnecessary forward declareThomas Hindoe Paaboel Andersen
2015-03-02core: expose consumed CPU time per unitLennart Poettering
This adds support for showing the accumulated consumed CPU time per-unit in the "systemctl status" output. The property is also readable via the bus.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-01-06core: add new logic for services to store file descriptors in PID 1Lennart Poettering
With this change it is possible to send file descriptors to PID 1, via sd_pid_notify_with_fds() which PID 1 will store individually for each service, and pass via the usual fd passing logic on next invocation. This is useful for enable daemon reload schemes where daemons serialize their state to /run, push their fds into PID 1 and terminate, restoring their state on next start from the data in /run and passed in from PID 1. The fds are kept by PID 1 as long as no POLLHUP or POLLERR is seen on them, and the service they belong to are either not dead or failed, or have a job queued.
2014-11-30core: warn and ignore SysVStartPriority=Zbigniew Jędrzejewski-Szmek
Option was being parsed but not used for anything.
2014-10-28core: send sigabrt on watchdog timeout to get the stacktraceUmut Tezduyar Lindskog
if sigabrt doesn't do the job, follow regular shutdown routine, sigterm > sigkill.
2014-09-19socket: introduce SELinuxContextFromNet optionMichal Sekletar
This makes possible to spawn service instances triggered by socket with MLS/MCS SELinux labels which are created based on information provided by connected peer. Implementation of label_get_child_mls_label derived from xinetd. Reviewed-by: Paul Moore <pmoore@redhat.com>
2014-09-08service: hook up custom endpoint logicDaniel Mack
If BusPolicy= was passed, the parser function will have created an ExecContext->bus_endpoint object, along with policy information. In that case, create a kdbus endpoint, and pass its path name to the namespace logic, to it will be mounted over the actual 'bus' node. At endpoint creation time, no policy is updloaded. That is done after fork(), through a separate call. This is necessary because we don't know the real uid of the process earlier than that.
2014-08-22core: add support for a configurable system-wide start-up timeoutLennart Poettering
When this system-wide start-up timeout is hit we execute one of the failure actions already implemented for services that fail. This should not only be useful on embedded devices, but also on laptops which have the power-button reachable when the lid is closed. This devices, when in a backpack might get powered on by accident due to the easily reachable power button. We want to make sure that the system turns itself off if it starts up due this after a while. When the system manages to fully start-up logind will suspend the machine by default if the lid is closed. However, in some cases we don't even get as far as logind, and the boot hangs much earlier, for example because we ask for a LUKS password that nobody ever enters. Yeah, this is a real-life problem on my Yoga 13, which has one of those easily accessible power buttons, even if the device is closed.
2014-08-21core: allow informing systemd about service status changes with RELOADING=1 ↵Lennart Poettering
and STOPPING=1 sd_notify() messages
2014-07-07core: Added support for ERRNO NOTIFY_SOCKET message parsing, and added ↵Miguel Angel Ajo
StatusErrno dbus property along StatusText to allow notification of numeric status condition while degraded service operation or any other special situation.
2014-07-03core: introduce new RestartForceExitStatus= service settingLennart Poettering
This does the inverse of RestartPreventExitStatus=: it forces a restart of a service when a certain exit status is returned by a service process.
2014-06-07Remove sysv parser from service.cThomas Hindoe Paaboel Andersen
Parsing sysv files was moved to the sysv-generator in the previous commit. This patch removes the sysv parsing from serivce.c. Note that this patch drops the following now unused sysv-specific info from service dump: "SysV Init Script has LSB Header: (yes/no)" "SysVEnabled: (yes/no)" "SysVRunLevels: (levels)"
2014-06-05core: introduce new Restart=on-abnormal settingLennart Poettering
Restart=on-abnormal is similar to Restart=on-failure, but avoids restarts on unclean exit codes (but still doing restarts on all obviously unclean exits, such as timeouts, signals, coredumps, watchdog timeouts). Also see: https://fedorahosted.org/fpc/ticket/191
2014-04-24service: rename StartLimitAction enum to FailureActionMichael Olbrich
It's used for the FailureAction property as well.
2014-04-24service: add FailureAction= optionMichael Olbrich
It has the same possible values as StartLimitAction= and is executed immediately if a service fails.
2014-04-21service: add support for reboot argument when triggered by StartLimitAction=Michael Olbrich
When rebooting with systemctl, an optional argument can be passed to the reboot system call. This makes it possible the specify the argument in a service file and use it when the service triggers a restart. This is useful to distinguish between manual reboots and reboots caused by failing services.
2013-12-01service: remove unneccesary Socket.got_socket_fdShawn Landden
2013-11-27service: add the ability for units to join other unit's PrivateNetwork= and ↵Lennart Poettering
PrivateTmp= namespaces
2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.
2013-10-19mount/service: drop FsckPassNo supportTom Gundersen
We now treat passno as boleans in the generators, and don't need this any more. fsck itself is able to sequentialize checks on the same local media, so in the common case the ordering is redundant. It is still possible to force an order by using .d fragments, in case that is desired.
2013-09-12service: Implement 'on-watchdog' restart optionHannes Reinecke
Services using the watchdog option might want to be restarted only if the watchdog triggers.
2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).
2013-05-02Add __attribute__((const, pure, format)) in various placesZbigniew Jędrzejewski-Szmek
I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.
2012-08-22service: introduce a proper service result if the start limit is hitLennart Poettering
2012-08-14service: add options RestartPreventExitStatus and SuccessExitStatusLukas Nykryn
In some cases, like wrong configuration, restarting after error does not help, so administrator can specify statuses by RestartPreventExitStatus which will not cause restart of a service. Sometimes you have non-standart exit status, so this can be specified by SuccessfulExitStatus.
2012-08-08systemd: introduced new timeout typesMichal Sekletar
Makes possible to specify separate timeout for start and stop of the service. [ Improved the manpage. Coding style fix. -- michich ]
2012-07-20unit: split off KillContext from ExecContext containing only kill definitionsLennart Poettering
2012-07-19use #pragma once instead of foo*foo #define guardsShawn Landden
#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
2012-06-15service: timeout for oneshot servicesLukas Nykryn
Add possibility to specify timeout for oneshot services. [ https://bugzilla.redhat.com/show_bug.cgi?id=761656 Added minor fixups. -- michich ]
2012-05-22units: remove service sysv_path variable and replace it by generic unit_pathLennart Poettering
UnitPath= is also writable via native units and may be used by generators to clarify from which file a unit is generated. This patch also hooks up the cryptsetup and fstab generators to set UnitPath= accordingly.
2012-04-24service: introduce Type=idle and use it for gettysLennart Poettering
Type=idle is much like Type=simple, however between the fork() and the exec() in the child we wait until PID 1 informs us that no jobs are left. This is mostly a cosmetic fix to make gettys appear only after all boot output is finished and complete. Note that this does not impact the normal job logic as we do not delay the completion of any jobs. We just delay the invocation of the actual binary, and only for services that otherwise would be of Type=simple.
2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
